Variability in the dual mycorrhizal associations of tea tree, Melaleuca alternifolia

Full description

This repository contains eight packed data files.

The quality-filtered otu tables and taxonomic annotation tables for arbuscular mycorrhizal fungi and ectomycorrhizal fungi, as well as the sample metadata sheet, can be used to run the reproducible statistical analysis workflow at GitHub.

Contents:

The

order: UNITE order annotation

family: UNITE family annotation

genus: UNITE genus annotation

species: UNITE species hypothesis annotation

pident: per cent sequence similarity to the reference sequence

length: alignment length of the query to the reference sequence (sequence overlap)

slen: query sequence length

mismatches: number of mismatches to the reference sequence

gapopen: number of gap openings relative to the reference sequence

The

taxa_AM.csv

order: order annotation based on consensus hit and similarity and coverage thresholds

family: family annotation based on consensus hit and similarity and coverage thresholds

genus: genus annotation based on consensus hit and similarity and coverage thresholds

species: genus annotation based on consensus hit and similarity and coverage thresholds

taxa_consensus: per cent consensus of BLAST hit across the five best hits

abundance: total OTU read abundance

similarity: per cent sequence similarity to the consensus sequence

coverage: per cent sequence coverage to the consensus sequence

evalue: evalue to the consensus sequence

ectomycorrhiza_exploration_type: inferred lineage of ectomycorrhizal fungi based on the FungalTraits database

ectomycorrhiza_lineage: inferred ectomycorrhiza exploration type based on the FungalTraits database

The

metadata.csv

file contains the following information:

sample: sample ID

ecotype: tea tree ecotype

site: site ID

col_AM: number of arbuscular mycorhizal observations per 60 cm of fine root
